Grayscale Filter

Solve It

The color white has red, green, and blue values all set to 255, and the color black has red, green, and blue values all set to 0. In general, when all three color values are equal, the result is some shade of gray. We will set all color components of each pixel to the average of the original three color component values.

Code It

// weighted grey scale var image = new SimpleImage("duvall.jpg"); for (var p of image.values()) { var avg = (p.getGreen() + p.getRed() + p.getBlue()) / 3; p.setRed(avg); p.setBlue(avg); p.setGreen(avg); debug(avg); } print(image);
